Method and apparatus for Chinese character text input

Abstract

A method and apparatus for inputting Chinese character text into a machine such as a word processor or personal computer. The system consists of an apparatus which forms a closed feedback loop with the operator. The operator supplies stroke selections and other data to the apparatus which presents character selection information in response to the user's input. As a consequence of the feedback provided to the operator and subsequent actions by the operator, the desired Chinese text is produced with significant improvements in speed and ease.

Description

FIELD OF THE INVENTION[0001]The present invention relates to input of Chinese character text using systems and apparatus such as word processors, computers and other similar devices.BACKGROUND OF THE INVENTION[0002]Several modern languages are written with scripts that utilize symbols known as Chinese characters. These symbols, which are also known as Han characters or ideographs, originated in China several thousand years ago. In the modern languages which use the symbols, the literal designations for “Chinese characters” vary, such as Hanzi (Chinese), Kanji (Japanese), and Hanja (Korean). The “modern” forms of the Chinese characters have been in continuous use for more than 15 centuries. Earlier forms were in use more than 30 centuries ago.[0003]The major languages that today utilize Chinese characters in their writing systems are Japanese, Korean and the numerous dialects of the Chinese language family (such as the more well known Mandarin or Cantonese). The Japanese and Korean l...

AI Technical Summary

Benefits of technology

[0031]The primary object of the present invention is to provide an improved method and apparatus for inputting Chinese character-based text into machines with minimum training and learning time, high efficiency and the elimination of the need for external references.

[0032]Another objective of the present invention is to retain the “word nature” of Chinese text by delivering completed words to the intended machine to facilitate the further “word processing” of Chinese text by retaining the operator's concepts of words as they are entered.

Problems solved by technology

All languages have fundamental units called words although what precisely constitutes a word in a particular language is often a subject of debate.

The problem, of course, is the difficulty remembering such a massive set of code numbers.

In the case of Chinese characters, however, the need to accommodate the many thousands of characters has been problematic.

There are, thus, many characters with essentially the same sound, and there are also difficulties in distinguishing many of the sounds for those with an active dialect that is different from Mandarin.

This approach, however, if applied too frequently can reduce the effectiveness of the system by resulting in less uniqueness.

Additionally, an operator who does not know the proper order and classification for a particular character must resort to the awkward and time consuming process of trial and error.

This can dramatically slow the overall average rate at which characters are inputted.

In this case the operator may be “stuck” and be forced to consult a reference.

Such systems using radicals all have relatively complicated coding systems, rigid rules and inflexible keyboard assignments and often organized into the, above-noted, multiple pages.

These factors make such systems difficult to learn and awkward to use.

None of the systems described in the prior art possess a completely satisfactory combination of ease of use, ease of learning the system and overall speed of text entry.
